` TO vALL WHOM IT MAY GONGERN:

Ble it known that I, ELIJAH BURTON, of Morris, in the county of Grundy, and State of Illinois, have invented a new and'useful Improvement in Pump-Levers; and I do hereby declare that the following is a full, clear, -and exact description thereof, which will enable others skilled in the art to ineke and use the same,` reference being had to the accompanying drawings, forming part ot' this specication.

i Y This invention relates to a new and improved method of operating the pistons or buckets of hand-pumps; and the invention consists in operating the pump by a cogged eccentric lever which engages with cogged segments, which also act eceentrically upon their centres, thereby imparting the required motion to the pump-rod, as will be hereinafter more, fully described.

Figure lurepresents a. side elevation of the pump, and- Figure 2 is a vertical section of' the same through theline :e az.

Similar letters of reference indicate corresponding parts.

Arepresents the pump. B represents the frame by whiclrthe segments and lever are supported, and also which support the guides for the pump-rod.- O is the pump-rod. D is the lever. E is a segment which is attached to the pump-rod by a pivot, a, through an arm. F is anotherscgment which is supported by the bedpiece of the frame, where it oscillates as-upon a centre at b. -f The lever D has two'semieircular gears attached to opposite sides of it eeeentrically, as seen in thedrawing. The. pump-rod is attached to theseg-ment E by i the pivot'a, through an arm, G, seen in tig. 1. Tho-pump-rod C is supported andguided-by the bracket H and -by the projecting cap-piece of thevframe, as seen at J.

It will be seen that the cogged segments E and F, as well as the segments on thelever, are eccentrics, and thatby depressing the lever D, as seen in the drawing, the segment E will be raised a distance corresponding with the combined throw of all the eccentries. The pumprod C bengconnected with E, will of course be raised the same distan-ce. The lever AD turns on ,the pinf, which works up and down in the slot z' in the uprights of the frame, as seen in the drawing. The inner standard of the frame B is slotted for the purpose of allowing the arrow G to move the full stroke given by the lever. In actual use, thepump-rod and the seg. ment E, with the water above the bucket or valve in the pump, will be of suiiicient weight to keep the segment inv contact with the eccentric on .the lever. s

By this arrangement it isese'en theta much greater movement of the pump-valve is produced-than can be by the lever-purchase of ordinary pumps. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The eccentric segment F-suppoi'tedat 6 uponl the bed-piece B, the eccentric semicircular gears upon the lever D sliding vertically in the slot ,the upper eccentric segment E sliding vertically in the slotted frame B', and pivoted to the arm G carrying the pump-rod C, al1 constructed and arranged to operate as herein, shown and described.
